You can always use `which' in the eshell buffer:

--8<---------------cut here---------------start------------->8---
~ $ which date
eshell/date is an alias for ‘current-time-string’ in ‘em-unix.el’.
~ $ which *date
/bin/date
--8<---------------cut here---------------end--------------->8---

And `which' itself is an eshell function:

--8<---------------cut here---------------start------------->8---
~ $ which which
eshell/which is a compiled Lisp function in ‘esh-cmd.el’.
~ $ which *which
/usr/bin/which
--8<---------------cut here---------------end--------------->8---

See also (info "(eshell) Built-ins")

Best regards, Michael.
